I like the comic, but the first panel on page 4 is worded oddly. We've just been told that studies subsequent to the one published in The Lancet failed to find any association between MMR and autism, then page 4 begins "This began a global health scare". The failure to find a link didn't begin a health scare - there needs to be a "however" in that panel, like "However, Wakefield's study began a global heath scare" or something similar.

That jarring note aside, good comic on an issue close to my heart.
